Hagon: From Speedway Frames to Shock Absorbers
Alf Hagon was an England international speedway rider and won 11 national grasstrack titles before founding Hagon Products in 1958 (Hagon Shocks). He started out building speedway and grasstrack frames in his mother’s garden shed, and from 1960 he ran the business from a former stable block in Leyton, East London (Wikipedia: Alf Hagon; Trakbytes Hall of Fame). Hagon frames used Girling shocks, and in 1977 Alf built what Motocross Action calls the first all-aluminum monocoque motocross frame. Alf was also a drag-racing record holder (Hagon Shocks).
In 1985, when Girling stopped making motorcycle shocks, Alf bought the former Girling suspension operation, including the stock, tooling and drawings. He didn’t buy the Girling name, so the shocks were sold as Hagon (Wikipedia: Alf Hagon; Trakbytes Hall of Fame). For more on Girling’s history, see Grace’s Guide.
From the 1980s, Hagon focused on twin shocks and rebuildable monoshocks. The company moved from its first shop on Leytonstone High Road to its factory at 7 Roebuck Road, Hainault, Essex. Alf’s son Martin, a European Grass Track Champion, runs the company today (Hagon Shocks). Hagon shocks are made at the Hainault factory, and road shocks are built for the rider’s weight and how the bike is used (Hagon Shocks: Manufacturing).
Hagon Shocks for Triumph Twins & Triples
Each pair has a black damper body, slimline chrome progressive springs, a double-sealed nitrogen cell, automatic compression and rebound damping, a hard chrome piston rod and a three-position preload adjuster. An adjuster spanner is included.
12.4-inch shocks
- Triumph 750 T140 and TR7, 1973–78, 100 lb (TBS-03-2004 SS): the standard length for 1973–78 Triumph 750 twins. They also fit unit 500 and 650 twins and Triumph and BSA triples from 1968 to 1975, lowering the rear by about 1/2″.
12.9-inch shocks
- Triumph 500 and 650 twins, 100 lb (TBS-03-3006 SS): the standard length for 1969–70 Triumph 650 twins and 1969–74 Triumph 500 twins. They also fit all unit 500, 650 and 750 Triumph twins up to 1978 and Triumph and BSA triples from 1968 to 1975.
- Triumph 500, 650 and 750 twins and Trident, 110 lb (TBS-03-3007 SS): Triumph 500 Daytona, Trophy and Tiger and 650 Bonneville, Tiger and Trophy from 1969, 750 T140 and TR7 from 1973 to 1978, and Triumph triples from 1969. The stiffer spring suits heavier riders or riding two-up.

Custom Order Hagon Shocks
We are a US distributor for UK-made Hagon shocks and can order Hagons for almost any motorcycle. Use the custom order form on this page and tell us:
- Your Hagon part number, if you know it
- Motorcycle make, model and year
- Rider weight, passenger weight and luggage weight in pounds
- How much of your riding is with a passenger
Hagon uses this information to choose the spring and damping for your bike (Hagon Shocks: Manufacturing). Our team will get back to you with pricing and details. Custom Hagon shocks are made to order, so once payment is complete they can’t be returned, refunded or exchanged.
How to Choose the Right Hagon Shocks
- Measure eye to eye. Measure your current shocks from the center of the top mounting eye to the center of the bottom eye. Most 1969 and later Triumph 500 and 650 twins use 12.9″, and the 1973–78 750 twins use 12.4″.
- Choose the spring rate. The 100 lb springs suit most solo riders. The 110 lb springs suit heavier riders, or riding with a passenger or luggage. For anything else, use the custom order form.
- Set the preload. Use the supplied spanner to adjust both shocks to the same setting, with the shocks fitted to the bike.
- Replace both shocks together. Shocks work as a matched pair.
- Check the mounting rubbers and hardware. Worn bushes and bolts spoil the ride of new shocks. See our Triumph rubber parts, Triumph hardware, Triumph frame fittings, BSA rubber spares, BSA hardware and suspension tools.
